Hi,
Is there a command to get the indices of intersecting elements of two
vectors as intersect() will give the elements and not its indices.
?which
samp1 <- sample(seq(3,198, by=3), 20); samp2 <- sample(seq(3,198,
by=3), 20)
int <- intersect(samp1, samp2)
int
#[1] 48 87 9 159 36 6 39 105
which(seq(3,198, by=3) %in% int)
#[1] 2 3 12 13 16 29 35 53
Thanks in advance.
